phrasing | Edit phrases inline for your Ruby on Rails applications | Application Framework library

Bear with me, I am new to posting and Rails so sorry if I mess up phrasing!!

I am working on a Rails app with many similar models. Each view has a _form.html.haml partial that differs in content but contains similar components, such as buttons to submit, delete, etc. Every model has_many_attached photos, and in the form you can add or delete photos. The haml for deleting photos looks like this, where variable is replaced with whatever view _form.html.haml is in:

I'm getting a very confusing error as I may be making a small mistake with the phrasing or the type handles or it could be a more complicated problem

Basically I want to create this funciton Buf_IO(HAL_StatusTypeDef IO) that can take one of two inputs either HAL_SPI_Transmit or HAL_SPI_Recieve

these are both defined as

Sorry for the bad phrasing of the question!

I created a function, abc, and it works fine with my data table, DT, by itself.

When playing around with C++20's concepts, I've found that when making a concept describing how a function should be (i.e. T must be a callable function that takes a size_t as argument), then using that concept in another template, the type of the function seems to be "lost". I don't really have a good way of phrasing it, so here's the code:

Hi. Please consider this code

My apologies if I am phrasing this question poorly.

Is there anywhere I can find a list of OpenGL/WebGL functions along with the targets they are associated with? For example, in order to call glDrawElements(), a buffer must be bound to the GL_ELEMENT_ARRAY_BUFFER target. And to call glBufferData(), a buffer must be bound to one of several targets, including GL_ARRAY_BUFFER, GL_ELEMENT_ARRAY_BUFFER, GL_UNIFORM_BUFFER, etc...

An alternative way to approach this question would be, Is there a list of targets with the functions they enable?

I've downloaded the OpenGL 3.0 ES documentation files and I am pretty confident that all the information I need is contained there. But it is spread across ~280 files and I know I'm going to miss a lot of instances. I must be overlooking something because this seems like such an important aspect of OpenGL when trying to grasp the concept of "targets".

TL;DR: What is the purpose and function of prepare(): void method of AWS CDK's Construct class? How and when am I supposed to use/avoid it?

The documentation on prepare() says:

Pseudo-code.

I'm new-ish to Swift, and trying to better understand Core Data with some (I thought!) simple projects.

I'm trying to use an @FetchRequest property wrapper to list child-items which belong to a given parent. This works for most cases, but not when the to-parent relationship is the only thing which would cause a child item to be displayed after a new child item is added.

The problem I'm facing seems to boil down to any filtering done with UUID values using predicates in FetchRequest decorators not being updated the same way other attributes are. The minimal example I've (with an edit) constructed shows just the behaviour when using a UUID for the predicate, and avoids any relationship complications.

My question is, is there a 'nice' way to make this behaviour (UUID in a predicate driving a FetchRequest which updates views properly) work, or something I'm missing, like registering one of the parts as an observed item, or something I'm doing triggering an update at the wrong time?

I have produced an example which illustrates the puzzle I'm having. Note: I'm using iOS 14.4 and Xcode 12.4 I appreciate these are not current, but my machine does not support an OS past Catalina, so I'm stuck here until I can afford a new one.

My Core Data model is as follows:

The Item entity has two attributes (uuid, of type UUID) and an Int16 attribute (number).

The app has two buttons: + to add a new item with a random number value and a fixed UUID of 254DC... and 5 which adds a item, with a number value of 5 (and the same, fixed, UUID).

The predicate[s] I'm using to drive this list filter Item entities which either:

• match the hard-coded UUID value*
• or have a number attribute of 5

The problem is that when adding (using the + button) a new entity which should show up in this view just because its uuid property matches, it does not appear. It does appear if you quit the app, and return to it (this proves that the predicate does indeed 'match' the UUID values).

After tapping 5 (now showing two rows with number 5, as expected):

After tapping + twice (unchanged view, should have two new rows showing):

If we exit the app and then reopen it, the added Items (300 and 304 in this case) are only now visible:

Different phrasing of the question: Why do these updates work unreliably on UUID, but perfectly with the number (Int16-typed) attribute?

Working as expected:

• Deleting Item entities works as expected, regardless of whether they were in the list because of number == 5 or their UUID match

Notes:

• I've used viewContext.perform liberally, as one other glitch with an update not displaying was resolved by using that.
• I had already (based on this SO question/answer) already tried wrapping each of the elements of the rows as an ObservedObject. This was also suggested in a comment. Have updated the example code to do that, which has no effect on this behaviour. (The elements are not in the items collection produced by the FetchRequest, so do not get wrapped by this code.)
• There is lots of try! all over the place. This is just to keep the example code as small as possible.
